' The tank ducedupperjend 18eXyternally threaded as at 20 to engageinternal threads at the lower fitting enolosed-within ahousping comprising avjbody'portion A andra cap provided with a base orLv internal partition i 21 having an opening .22 therein through which the pipe k8 extends: 'The support .12 f

is secured to the partition ."21 bybolts 13 Vwhich are threaded into tapped `lugs 17 support 12 andthe partition. `The support 12. 'is provided with?H an(y opening V through y which pipe 8 extends, and saidpipe is prefverably welded as at 10v to the support.

Theloweredge of the wall 16 is provided with an outwardly extending flange 24 which f is conformed to the shape of, or to be more specific, to the slope ofthe dome head` 2 and said langeli is securedtothe domek head 2 in any suitable manner. as by being welded or riveted .tothe head. As shown, :the insu? me. f

lation 4 extends to and surrounds the wall 16 for a portion of the height of the latter'. r'he reduced end i8 of the wall lli provides an offset 2G, thus defining an annular shoulder 28 which is preferably machined to furnish a seat for the flanged upper edge 30 of a hashing indicated generally at 32.

T he flashing 32 is annular in shape and the depth thereof conforms, of course, to the forni of the sheathing, said flashing being substantially Z-shaped in cross section and comprises a web 34, and a lower chord or outwardly extending flange 36 secured to the sheathing edge adjacent .an opening therein through which the body portion A extends; the securing means in the present instance being a weld 88. rlhe chord of the Z-shaped section comprises the flange 3() heretofore described which overlies lthe machined shoulder 38.

The cap B may be of any general shape but is shown as having an' upwardly tapered top portion 40 and a side wall 42, the lower end of the latter being provided with an internally arranged machined seat 34 and `with an-outwardly offset lower ange 35. rlheY cap is provided with internal threads to secure the cover to the reduced upper end of the body portion A. The parts are so proportioned that when the cover or cap B is in position the seat 44 Will engage the flange 30 of the flashing, and the flange 46 of the cover skirts the flashing as clearly shown in the drawing. Y

After the sheathing 6 has been applied to the insulation 4; the housing having beenV previously attached to thedome head 2, the flashing 82 is placed in position around the body portion A and it is welded to the sheathing 6 as shown at 38. lt is apparent that the flashing which is an annulus can be slipped over the body portion A into its proper position, and the flange 30 of the thrashing will overlie and preferably rest upon the machined seat or shoulder 28. `When thecap B is applied it is screwed down on the body portion A and the seat 44 will be urged against the flange 30 and hence a tight seal will be formed entirely around the shoulder 28 thereby providing a sealed joint which eectually prevents the admission of water to the insulation 4. t will also be apparent that in addition to the feature just mentioned the tight seal established by the seats 28 and 44 with the flange 8() prevents the escape of any gas `which may have leaked from the tank into the housing through the valve or through any opening which may be present from the interior of the dome into the housing;

that various changes in the form and proportions of the device may bemade within the scope of the appended claims without departing from the spirit of the invention.

What is claimed is:

2. ln an insulated container, an outer sheathing,A a housing body portionextending above the sheathing, a cap for the housing, and means forming a joint between the `sheathing and the body portion comprising a fiashing secured to the sheathing around the housing and having an upper annular flange overlyinga body portion part and clamped betweensaid housing part and the cap by said cap.

3'. In an insulated container, an outer sheathing, a housing body portion extended through the sheathing and having a shoulder formed intermediate the top and bottom edges thereof, a fiashing secured to the sheathing and having its upper edge overlying said shoulder, and a housing cap secured to the body portion and provided with an annular seat adjacent its lower end for engagement with the overlying portion of the flashing.

4. ln an insulated container, an outer sheathing, a housing body portion extended through the sheathing and having an eX- lternal shoulder formed intermediate its top and bottom edges, a flashing surrounding the housing body portion and secured to the sheathing and having its upper edge overlying said external shoulder, and a housing cap threadedly engaged with the body poryrio-n and provided with an internal annular seat adjacent its lower end adapted to engage the overlying portion of the flashing sheathing, a housing extended through the sheathing and provided with alremovable cap, said housingand cap each being formed with an annular seat which, when the cap and housing are assembled are opposite each other, and a flashing welded to the sheathing and arranged around the sheathing and having an inturned annular flange at its upper edge arranged between the seats and held against shifting by the housing cap.
